With the increase of environmental protection requirements and production process automation, its importance is becoming increasingly important. "Granular powder products" has become an inevitable trend in the world of powder post-treatment technology. Dry silver granulation has the advantages of low energy consumption, no need to add additional adhesive, low investment and wide range of capacity.
Art characteristics.
As a main branch of the process of powder particle processing, dry granulator is a kind of equipment that makes granulated materials after squeezing, crushing and finishing the powder materials. Dry granulation process is a new granulation technology in recent years. Its advantage is that it can be directly granulated without wetting, mixing, drying and other processes. The process is simple and can effectively guarantee the quality of traditional Chinese medicine.
Dry granulation machine is the use of crystal water in the material, directly into the powder into the new equipment, the machine structure is novel and reasonable, stable and reliable performance, easy cleaning and maintenance, the machine made of particles can be pressed tablets, do powder, glue, etc., the machine is mainly used in pharmaceutical, food, chemical and other industries granulation.
The significance of dry granulator for particle strength processing of powder products is mainly reflected in three aspects
(1) Reduce dust pollution, improve working conditions,
(2) The dry granulator meets the requirements of the production process, such as increasing the porosity and specific surface area, and improving heat transfer.
(3) Improve the physical properties of the product (such as fluidity, permeability, pile density) to avoid the subsequent operation process (drying, screening, measurement) and use process (measurement, batching, etc.) segregation, pulsation, agglomeration, bridging and other adverse effects, in order to improve the automation of production and use process, closed operation to create conditions.
The pelletizing process starts from the addition of thousands of powder materials from the top of the equipment, through degassing, spiral prepressing into the opposite roller, under the extreme extrusion pressure of the opposite roller, the material produces plastic deformation and is compressed into sheet, and the sheet material is then broken, whole grain, screening and other processes to obtain granular products. The size of the extrusion pressure can be adjusted by the pressure of the hydraulic cylinder according to the needs of the pelletizing operation. Different pressure Settings can obtain different strength of the finished particles.
